Learn How to Knit Boxers

Knitting your own boxers can be a fun and rewarding project for any knitting enthusiast. Not only do you get to create a comfortable and personalized pair of boxers, but you also get to showcase your knitting skills. In this step-by-step guide, we will walk you through the process of knitting boxers from start to finish.

Step 1: Gather Your Materials

Before you begin knitting your boxers, you will need to gather all the necessary materials. This includes knitting needles, yarn in your desired color and weight, stitch markers, scissors, and a tapestry needle. Make sure you choose a soft and breathable yarn, as comfort is key when it comes to underwear.

Step 2: Take Measurements

Next, you will need to take accurate measurements of the person who will be wearing the boxers. Measure their waist, hips, and the desired length of the boxers. This will ensure a proper fit and prevent any unwanted surprises when the project is complete.

Step 3: Cast On and Knit the Ribbing

Once you have your measurements, it’s time to cast on and start knitting the ribbing. Knit a few rows of ribbing using a smaller needle size to create an elastic waistband. This will help the boxers stay in place and provide a comfortable fit.

Step 4: Knit the Body

After completing the ribbing, switch to larger needles and continue knitting the body of the boxers. Use a stitch marker to indicate the beginning of each row and follow the pattern or design you have chosen. Be mindful of the measurements you took earlier to ensure the boxers will fit properly.

Step 5: Shape the Crotch

Once the body is complete, it’s time to shape the crotch area. This will create a comfortable and anatomically correct fit. Follow the instructions in your pattern or use shaping techniques such as decreases and increases to achieve the desired shape.

Step 6: Finish the Leg Openings

Lastly, finish the leg openings by either knitting ribbing or using a stretchy bind off technique. This will help the boxers stay in place and provide a neat and professional finish. Weave in any loose ends using a tapestry needle and trim off any excess yarn.

With these steps, you now have a basic understanding of how to knit boxers. Feel free to experiment with different patterns, colors, and yarns to create unique and custom designs. Knitting boxers can be a fun and practical way to indulge in your love for knitting while creating a handmade garment that is both stylish and comfortable.

Choosing the Right Yarn and Needles for Knitting Boxers

When it comes to knitting boxers, choosing the right yarn and needles is crucial to ensure a comfortable fit and sturdy fabric. Here are some factors to consider when selecting your materials:

Yarn Weight

Yarn weight determines the thickness of the yarn and, consequently, the stitch size and fabric density. For knitting boxers, it is recommended to use a medium-weight yarn, such as worsted or sport weight. These yarn weights provide a good balance between breathability and durability.

Yarn Fiber

The choice of yarn fiber can greatly impact the breathability, softness, and stretchiness of the finished boxers. Natural fibers, such as cotton, bamboo, or linen, are excellent options for their breathability and softness against the skin. Avoid using acrylic or synthetic fibers, as they tend to be less breathable.

Needle Size

The needle size you choose will depend on the yarn weight and the desired fabric density. For medium-weight yarns, a needle size between US 6 (4mm) and US 8 (5mm) is commonly used. However, it is essential to check the yarn label for manufacturer’s recommendations to ensure the best gauge and fabric characteristics.

Circular Needles

While traditional straight needles can be used for knitting boxers, circular needles offer some advantages. They allow you to knit in the round seamlessly, eliminating the need for seaming later. Additionally, circular needles distribute the weight of the project more evenly, reducing strain on your hands and wrists.


In addition to yarn and needles, you may need some notions for knitting boxers. These can include stitch markers, a tape measure, scissors, and a row counter. Stitch markers are particularly helpful for marking the beginning of the round when knitting with circular needles.

Knitting Gauge

Before beginning your project, it is crucial to swatch and measure your gauge. This involves knitting a small sample using the chosen yarn and needles and measuring how many stitches and rows fit within a given measurement. The recommended gauge for knitting boxers is typically provided in the pattern or yarn label. By matching the gauge, you ensure that the final product will have the desired dimensions and fit.

In conclusion, selecting the appropriate yarn and needles for knitting boxers is essential for achieving a comfortable and well-fitting garment. Consider the yarn weight, fiber, needle size, and knitting gauge to ensure a successful project.

Basic Knit and Purl Stitches for Knitting Boxers

When knitting boxers, it’s important to be familiar with the basic knit and purl stitches. These stitches form the foundation of any knitting project, including boxers. Here’s a step-by-step guide on how to knit these essential stitches:

  1. Knit Stitch:
  2. The knit stitch is the most basic stitch in knitting and is often abbreviated as “k” in knitting patterns. To knit a stitch, follow these steps:

    • Hold the knitting needles with the stitches in your left hand and the empty needle in your right hand.
    • Insert the right-hand needle into the first stitch on the left-hand needle from left to right.
    • Wrap the yarn around the right-hand needle counterclockwise, bringing the yarn to the front of the work.
    • Draw the right-hand needle through the stitch, bringing the new stitch onto the right-hand needle and dropping the old stitch off the left-hand needle.
    • Repeat these steps for each stitch in the row.
  3. Purl Stitch:
  4. The purl stitch is another fundamental stitch in knitting and is often abbreviated as “p” in knitting patterns. To purl a stitch, follow these steps:

    • Hold the knitting needles with the stitches in your left hand and the empty needle in your right hand.
    • Insert the right-hand needle into the first stitch on the left-hand needle from right to left.
    • Wrap the yarn around the right-hand needle counterclockwise, bringing the yarn to the back of the work.
    • Draw the right-hand needle through the stitch, bringing the new stitch onto the right-hand needle and dropping the old stitch off the left-hand needle.
    • Repeat these steps for each stitch in the row.
  5. Working with a Combination of Knit and Purl Stitches:
  6. Depending on the pattern for your boxers, you may need to alternate between knit and purl stitches. This creates different stitch patterns, such as ribbing or seed stitch, which add texture and stretch to the fabric. Follow the pattern instructions to determine when and how to switch between knit and purl stitches.

  7. Practice and Testing:
  8. Before starting to knit your boxers, it’s a good idea to practice knitting and purling on a small sample swatch. This allows you to familiarize yourself with the stitches and gauge your tension before working on the actual project. Additionally, you can test different stitch patterns to see which ones you prefer for your boxers.

By mastering the knit and purl stitches, you’ll be able to create beautiful and comfortable boxers that showcase your knitting skills. Happy knitting!

Shaping and Decreasing for a Better Fit

One of the key steps in knitting boxers is shaping and decreasing to ensure a better fit. This involves creating a slimmer waistband, narrower leg openings, and a more form-fitting shape overall. Here are the steps to achieve this:

  1. Start by knitting the waistband to the desired width. This will determine the circumference of the boxer’s waist.
  2. Next, transition into the body of the boxer by decreasing the number of stitches. This creates a tapered effect, making the waist smaller.
  3. To decrease the stitches, you can use techniques such as knitting two stitches together (k2tog) or slipping stitches (sl1, k1, psso). These decreases should be evenly distributed across the row.
  4. After decreasing for the waist, continue knitting the body of the boxer to the desired length.
  5. Next, shape the leg openings by decreasing the number of stitches. This creates a snugger fit around the thighs.
  6. To decrease for the leg openings, you can use the same techniques as for the waistband. Again, distribute the decreases evenly along each row.
  7. Once you have completed the shaping and decreasing, finish off the boxer by knitting a ribbed or garter stitch hem at the leg openings.

Remember to measure your own body or follow a sizing chart to ensure the boxers fit you properly. Also, it’s important to consider the type of yarn and gauge you are using, as these factors can affect the fit of the boxers.

With these shaping and decreasing techniques, you can create boxers that are tailored to your body shape, providing a comfortable and flattering fit.

Adding the Elastic Waistband to your Knitted Boxers

After you have completed knitting the body of your boxers, it’s time to add the elastic waistband for a comfortable fit. Follow these steps to ensure a proper finish:

  1. Measure the waistband: Use a measuring tape to determine the desired length of your elastic waistband. It should fit snugly around your waist without feeling too tight.
  2. Cut the elastic: Using a pair of sharp scissors, carefully cut the elastic to match the measurement you took in the previous step.
  3. Sew the ends: Take one end of the elastic and overlap it with the other end, creating a loop. Use a sewing machine or hand stitch to securely sew the ends together. Make sure the seam is strong and won’t come apart with wear.
  4. Mark the waistband: Place the looped elastic around the top edge of your boxers. Use fabric chalk or a fabric marker to make small marks at equal intervals around the waistband. These marks will serve as guidance for attaching the elastic evenly.
  5. Pin the elastic: Starting at the back center of the waistband, insert a pin through one of the marked points on the elastic and into the fabric. Continue pinning all the way around the waistband, making sure to stretch the elastic evenly as you go.
  6. Sew the elastic: Using a sewing machine or a stretch stitch on your regular sewing machine, carefully sew the elastic to the top edge of the boxers. Be sure to stretch the elastic as you sew to ensure a snug fit.
  7. Trim the excess: Once you have sewn the elastic all the way around the waistband, trim any excess elastic that extends beyond the edge of the fabric.

Your knitted boxers are now complete with a comfortable and secure waistband. Try them on to experience the perfect fit and enjoy the comfort of your handmade creation!

Knitting the Leg Openings and Hemming the Bottom

Once you have finished knitting the body of the boxer shorts, it’s time to work on the leg openings and hem the bottom. Follow these steps to achieve the desired results:

  1. With the right side facing you, pick up stitches along one of the leg openings. Use a circular needle or double-pointed needles to evenly distribute the stitches.
  2. Knit in the round for a few rows to create a ribbed or rolled edge. You can choose the number of rows based on your preferences.
  3. Repeat steps 1 and 2 for the other leg opening.
  4. Next, you’ll need to hem the bottom of the boxers. Fold the bottom edge up towards the inside of the garment, about 1 inch or your desired hem width.
  5. Secure the hem by stitching it in place using a tapestry needle and the same yarn you used for knitting the boxers.
  6. If desired, you can add a decorative touch to the leg openings and hem by using a contrasting color yarn or adding a picot edge.

Once you have completed the leg openings and hem, you can weave in any loose ends and give your boxers a final press with an iron if necessary. Your knitted boxers are now ready to be worn or gifted!

Finishing Touches: Weaving in Ends and Blocking

Once you’ve completed knitting your boxers, it’s time to give them the finishing touches. This involves weaving in any loose ends and blocking the fabric to give it a nice, polished look. Follow these steps to achieve the best results:

  1. Weaving in Ends: Start by threading a tapestry needle with the tail of your yarn. Then, insert the needle into the back of your stitches along the edge of the fabric. Weave the needle back and forth, going under the stitches, until the tail is securely hidden. Repeat this process for any other loose ends.
  2. Blocking: Blocking is a technique used to shape and stretch your knitted fabric to achieve the desired measurements. Fill a basin with lukewarm water and add a small amount of wool wash or gentle soap. Place your boxers in the water and gently press them down to soak. Let them sit for about 15 minutes.
  3. Removing Excess Water: After soaking, carefully lift your boxers out of the water and gently squeeze out the excess water. Avoid wringing or twisting the fabric, as this can cause stretching or deformation.
  4. Shaping and Pinning: Lay your boxers on a clean towel or blocking board. Use your hands to gently shape them into the desired size and shape. Smooth out any wrinkles or uneven edges.
  5. Pinning: Once you’re happy with the shape, use rustproof T-pins to secure the fabric in place. Start by pinning the corners and edges, and then work your way around, spacing the pins evenly. This will help the fabric maintain its shape as it dries.
  6. Drying: Leave your boxers to dry completely. It’s best to lay them flat rather than hanging them, as this can cause stretching. Depending on the climate and humidity, drying may take anywhere from a few hours to a day or two.
  7. Removing Pins: Once your boxers are fully dry, carefully remove the T-pins. Be gentle to avoid snagging or damaging the fabric.

Congratulations! You’ve successfully finished your knitted boxers by weaving in ends and blocking. Now they are ready to be worn or gifted to someone special.

Tips and Tricks for Knitting Boxers: Troubleshooting and Customization

Knitting boxers can be a fun and rewarding project, but it’s not without its challenges. Here are some tips and tricks to help you troubleshoot common issues and customize your boxers to fit your preferences.


  • Problem: Uneven stitches or tension issues.
  • Solution: Pay close attention to your tension while knitting. Make sure to use the same tension throughout the entire project. If you notice uneven stitches, try using a different needle size or adjusting your tension.
  • Problem: Twist or gap in the stitches.
  • Solution: When knitting in the round, it’s important to ensure that your stitches are not twisted on the needle. Take extra care when joining your work in the round to avoid this issue. If you notice a gap between stitches, you can tug on the yarn slightly to close it up.
  • Problem: Boxers are too loose or too tight.
  • Solution: To customize the fit of your boxers, you can adjust the pattern by adding or subtracting stitches. If the boxers are too loose, consider decreasing the number of stitches in the waistband or legs. If they are too tight, try increasing the number of stitches.


Make your boxers unique by customizing them to your liking!

  • Choose your yarn: Select a yarn that is comfortable and breathable. Consider using a natural fiber like cotton or bamboo for optimal comfort.
  • Add a personal touch: Embellish your boxers by adding a contrasting color yarn for the waistband and cuffs. You can also experiment with different stitch patterns or add a monogram for a personalized touch.
  • Adjust the length: If you prefer longer or shorter boxers, you can easily modify the pattern by adding or subtracting rows. Remember to adjust the shaping accordingly.
  • Consider different closures: Instead of an elastic waistband, you can try using a drawstring or a ribbed waistband for added comfort and style.

With these tips and tricks, you’ll be well-equipped to troubleshoot any issues that may arise while knitting boxers. And don’t be afraid to get creative and customize your boxers to make them uniquely yours!
